I'm wanting to construct a code using pylab import that shows how sound is affected by speed of sound underwater and how the temperature underwater in April at different oceanic depths and latitudes influences sound.

Speed of sound underwater equation: c = 1448.96 + 4.591T 5.304 10²T² + 2.374 10⁴T³ + 1.340(S 35) + 1.630 10²D + 1.675 10⁷D² 1.025 10²T (S 35) 7.139 10¹³T D³.

c = speed of sound in m/s

t = temp C

s = salinity 35 ppt 1000 grams

d = depth

the latitude of the ocean is between: 10S and 60S

temp: different at different depths and latitudes depth:

zone 1 (surface of the ocean) 0 to 200m

zone 2 (thermocline) 200 to 1000m

zone 3 (deep part of the ocean) 1000m +

In April, (Tsurface) is linear of the absolute value of the latitude; 2C at the poles - 25C at equator

(Tdeep part of the ocean) is 2C regardless of the latitude, and is a continuous function of the depths

The thermoclines temp must change with depth

The surface temperature is a linear function of latitude. Use top points 200 m for Tsurface and the bottom point 1000 m for Tdeep in the thermocline to determine the linear model for the temperature in zone 2.

The code can include only arrays, loops, floats, strings, calculations/conversions, variables, functions, conditionals, true or false statements boolean, else, elif, if statements, def, deg, and graphs.
